Figure 10 (a-j): Tuberculous meningitis with tuberculoma. T2W (a) as well as T1W (b) images show no apparent changes in the brain parenchyma. Magnetization transfer (MT) T1W (c) and postcontrast T1W (d) images in the initial study show meningeal enhancement (arrows). Color-coded fractional anisotropy (FA) map modulated by the principal eigenvector (e) shows increased FA values (arrow) in the cerebral cortical region that showed meningeal enhancement. After 3 months of antituberculous treatment, the patient developed a lesion in the right thalamic region, visible on T2W (f), T1W (g), MT T1W (h), and postcontrast T1W (i) images, consistent with a tuberculoma. The abnormalities in the subcortical region (arrow) appear to have reversed on the postcontrast T1W image (i) as well as on the color-coded FA maps (j)
